In some implementations, a potentiometer (not shown) may be operably connected to the control circuit and the potentiometer may control the PWM signal.
In some implementations, the mechanism 1102 for holding LEDs is a plurality of horizontal rows. In some implementations, the angle of each horizontal row differs from the angle of its adjacent horizontal row. This may result in the LEDs being pitched.

As explained above, an optional latch 248, 250 may be present to secure the lighting device 200 to another lighting device 200 or other object having a corresponding mechanism 262, 264 suitably positioned to make contact with the latch 248, 250.
In some implementations, the latch 248 may automatically engage when lighting device 200a is placed on top of lighting device 200b and the latch 248 is substantially aligned with mechanism 264. In some implementations, the latch 248 may be manually engaged when the lighting device 200a is placed on top of lighting device 200b and the latch 248 is substantially aligned with mechanism 264. In some implementations, a user of the lighting device may manually operate the latch 248 by grasping or pressing the latch 248 at location 1802.

In some implementations, the mechanical connector may be integrated into the lighting devices.
In some implementations, the lighting devices may be capable of being controlled through a remote control via infrared (IR) signals or radio signals. In some implementations, one remote control may control one, more than one, or all of the lighting devices operably connected to each other.

A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosures in this application. As a non-limiting example, additional components may be added to those described above, or components may be removed or rearranged. It is understood by one skilled in the art that the connections and attachments described in this disclosure may be direct or indirect connections and attachments, respectively.

In some implementations, the lighting device may have 30 LEDs with each LED being 1″ apart from its adjacent LED. In some implementations, the lighting device may have more than 30 LEDs. In some implementations, the lighting device may have less than 30 LEDs. In some implementations, each LED is spaced less than 1″ apart from its adjacent LED. In some implementations, each LED is spaced apart more than 1″ from its adjacent LED.
As another non-limiting example, in some implementations, the mechanism for connecting the lighting device 200 to at least one other lighting device 200 or other object may be a nut, a bolt, a dowel, a lug, a pin, a rivet, a screw, a hook-and-loop fastener, a snap-lock mechanism, a press-fit mechanism, a bracket-type mechanism, a slide-and-lock mechanism, a twist-and-lock or other friction-fit mechanism, a tongue-and-groove mechanism, a buckle mechanism, a joint, or any other suitable mechanism for securing the lighting device 200 to at least one other lighting device 200 or other object.

The optic or lens may enable light being emitted from an LED to be emitted at an angle different from the angle corresponding to the angle upon which the LED is mounted. In some implementations, a lighting device may have a plurality of LEDs on the same or substantially the same plane and an optic or lens optically redirects the light so that the light being emitted may be substantially the same as if the LEDs were not all mounted in the same or substantially the same plane. In some implementations, an optic or lens may permit the light being emitted from the lighting device to be emitted in a shape or design, including, but not limited to, a circle, star, square, oval, rectangle, triangle, moon, or any other shape or design.
